摘要： It is suggested to machine contaminated surfaces, in particular radioactively contaminated concrete surfaces and masonry with pneumatically actuated striking tools. It has been shown that this is an extremely low-dust machining method with which the essentially the particles are struck off in the size order of 0.2 to 2.0 mm.The method may be realized with a device (1) with which in a housing (2) several chambers are arranged over one another. Most preferred at the top a pressurized air feed chamber (10) is fed via a pressurized air connection (3). Therebelow there is located a pressurized air suction chamber (12) which comprises a suction connection (4). At the bottom there is arranged a collecting chamber in which chisel-like hammer bolts (51) are effective. The hammer bolts which are part of the striking tools (5) project out of the housing (2). The striking tools (5) pass through the pressurized air feed chamber (10), the suction chamber lying thereunder as well as an expansion chamber arranged under the suction chamber (12). The expanded air (11) reaches the surroundings and is in turn suctioned via the collecting chamber (13) which is limited to the surroundings by way of an air-permeable seal in the form of a brush seal (9). The device (1) is held by a clip (6) on which there is provided a mounting (7) which serves for connecting to a robot arm.

摘要： A dust extractor for a drill includes a housing having an engagement region for receiving the drill when connected to the dust extractor; and a latch mechanism. The latch mechanism includes a latch moveably mounted within the housing and moveable between a first position and a second position, a biasing mechanism biasing the latch towards the first position, and a catch attached to the latch. The catch has a chamfer which is arranged so that the chamfer slidingly engages the drill and moves the latch from its first position towards its second position when the drill enters the engagement region.

摘要： The dust removal device comprises a fan (18), a dust collection receptacle (24), and a suction passage (28). The dust collection receptacle (24) equipped with a dust filter (26) is located in the path of air flow (34, 36) between the suction passage (28) and the fan (18). The dust is therefore filtered out of the air stream before it reaches the fan, which prevents dust-induced wear. It is also possible to use the same fan for engine cooling as well as dust removal.

摘要： An extracting device (4) for removing material cut away in the operation of a motor-driven hand tool, has an extracting opening (48) and a receiving space (18) for the cut material, which communicate with one another through an extracting path, and an air current generator (42) for generating an air current (L) from the extracting opening (48) to the receiving space (18). A closure device (20) is provided between the extracting opening (48) and the receiving space (18), which at least substantially places the extracting path in a closed position and which is operated by the air current (L). The closure device (20) is arranged between the extracting opening (48) and the air current generator (42) and the closure device (20) has a closure element (22), which can be removed from a valve seat (24) by means of an underpressure created by the air current generator (42) for forming an open position of the closure device.

摘要： A power tool, particularly a hammer drill, is equipped with a blower which is mounted on the output shaft of the motor which drives the tool element which is clamped in the chuck of the power tool. The particulate material which is removed by the tool element from a structure is entrained in a stream of air generated by the blower and conveyed toward the latter. Before the particulate material enters the blower, at least most of it impacts an impact member which extends across an inlet section of the conduit through which the stream of air passes, so that the impact member deprives the entrained particulate material at least of the greater part of the kinetic energy possessed thereby, before the particulate material reaches the blower and damages the same due to its high kinetic energy. The particulate material entrained in the stream of air may be collected in a collecting receptacle which is detachably connected to the power tool, and a plate-shaped filter may be arranged between the space bounded by the receptacle and the downstream portion of the conduit, being supported on a grid of pins which between themselves define openings which communicate with the downstream portion of the conduit.
